Here is a little function to add an element to a structure field:

    /**
     * Add a new element to a kirby structure field
     * @param string $page
     * @param string $field
     * @param array $data
     */
    function addToStructure($page, $field, $data = array()){
      $fieldData = page($page)->$field()->yaml();
      $fieldData[] = $data;
      $fieldData = yaml::encode($fieldData);
      try {
        page($page)->update(array($field => $fieldData));
        return true;
      } catch(Exception $e) {
        return $e->getMessage();
      }
    }
